    ok. let's start with the left one. There's a 10 that's subtracted. How can you cancel it out (aka move it to the other side of the equation)?

    right, so now you need to cancel the 2 to find your x

    same steps you used before. Add 10 to -26 then divide by 2

    divide both sides AFTER you add the 10 to both sides

    I can't see what you're doing, so I'm not sure we're talking about the same equation. Can you use the draw tool to show me what you have?

    When we solved the other equation we added 10 first. (see the one on the left.) Do the same thing for the equation on the right |dw:1435069181874:dw|

    yes. on the left equation we got 18. but there are 2 solutions. We need to solve the equation on the right. What do you get when add 10 to -26 on this|dw:1435069483961:dw|

    2(18) - 10 = 26. That works for one answer. The absolute value equation has 2 solutions. 18 is the solution for 26. We need to find the solution for -26.

    If you notice all your options have 2 numbers. Do you see what I'm saying?

    @peachpi i multiplied 2 with 18 and subtracted 10 and got 26

    That's what we're solving this for. What do you get if you add 10 to -26? |dw:1435070054490:dw|
